Next-generation data protection and integrityWhen dealing with large-scale data storage, businesses require a solution that offers reliable backup and prevents file corruption. With support for the next-generation Btrfs file system, DS3617xs ensures information is stored with a high level of data integrity, while providing flexible and efficient data protection tools. See the white paper for more technical details regarding Btrfs and data protection.

Fast and efficient snapshotsSnapshots preserve the history of a shared folder allowing you to save up to 1024 backup copies for point-in-time recovery. Snapshots can be automatically captured up to every 5 minutes, without noticeably impacting system performance.

Metadata mirroring and survivabilityBtrfs file system stores two copies of critical metadata on a volume, improving the availability and ensuring the integrity of your file system.

Corruption detection and correctionBtrfs generates checksums for data and metadata, and then verifies the checksums during each read process to ensure the integrity of the filesystem and files. If the file system discovers a mismatch, metadata will be repaired to keep file system consistent. In the meantime, corrupted files will be reported and logged.

Customizable quotas for shared foldersWith Btrfs, you can specify a storage limit for each shared folder, making it possible to precisely control space consumption when multiple teams or departments save files on the same Synology NAS server.

Protection with LUN backup, snapshot, and cloneDS3617xs enhances the ease of moving and copying data in a virtualized environment with the features LUN Snapshot, clone, and replication. Synology’s LUN Clone and LUN Snapshot only consume 1/1000 of the original size highly optimizing storage usage. In addition, Synology's LUN Snapshot lets you create up 256 snapshots per LUN using point-in-time technology without having any impact on system performance. With better support to servers under VMware vSphere or Windows environment, IT managers can expect guaranteed VM status and data consistency through application-consistent snapshots. FeaturesScale on demandDS3617xs can be connected to one or two dedicated DX1215 expansion units, allowing you to expand storage capacity to up to 36 drives without disrupting service. The high-bandwidth cable ensures instant and lossless connections between the main server and the expansion units.

10GbE upgradabilityIn addition to the four built-in Gigabit ports, DS3617xs comes with a PCIe 3.0 x8 slot to support an optional 10GbE Network Interface Card (NIC), maximizing bandwidth and meeting high performance requirements for data-intensive applications.

Reliable redundancy mechanismsDS3617xs comes with comprehensive redundancy mechanisms to ensure business continuity. Built-in four LAN ports with failover provides reliable redundancy in the event of unexpected network failure. The high reliability system design, including fanless CPU heat-sink and passive cooling technologies, prevents a single point of failure.
